About

A bit about me

Full Stack, Security, Hacking, Reverse Engineering and comfortable owning a project end to end.

I’m a Full Stack Engineer specializing in AI, Blockchain, Web, and Mobile development, with deep expertise as a Security Researcher focused on Reverse Engineering and Ethical Hacking.

I design and build end-to-end systems from intelligent AI-powered backends and smart contracts to responsive web applications and cross-platform mobile apps. On the security side, I conduct reverse-engineer software for defensive purposes, and perform ethical penetration testing to strengthen systems against real-world threats.

My work sits at the intersection of cutting-edge technology and practical security, helping teams ship robust, scalable, and secure products.
